I have used Google Inbox, but if I read the comments here, the overarching thing seem to be to make a zero inbox. Why cannot you do this with your existing email client? What are the features of Google Inbox that helps you do this? And why do you need to make your inbox zero? Is it like you want the email client to show up the high priority ones that you need to attend to at the top? How does a Google Inbox automatically know what is high priority for you ? Sorry if my understanding is not aligned to what is offered by Google Inbox.
